Abstract

The aim of this study was to identify and evaluate novel prognostic markers for gastric cancer. Differential mRNA displays comparing paired tumor/normal stomach samples were assessed. Several differentially expressed cDNA fragments of candidate genes were identified, and one of these was further studied using quantitative reverse transcription-PCR in 140 human gastric carcinomas. To evaluate protein expression, immunohistochemical staining was performed in selected cases. One of the genes abundantly expressed in tumor tissue on the differential mRNA displays was identified as histone deacetylase 1 (HDAC). HDAC was overexpressed in the tumor tissue in 77% of the cases as determined by quantitative reverse transcription-PCR. Immunohistochemical staining revealed analogous results, showing strong expression in cancer cells. Patients were then classified into high (n=78) and low (n=62) expression groups according to the mean value of HDAC expression. High frequencies of lymph vessel and vascular vessel permeations, and advanced stage of the disease were recognized in the high expression group compared to the low expression group (p<0.05). Prognosis was significantly worse for the high expression group than for the low expression group (p<0.05), and multivariate analysis demonstrated that HDAC expression was an independent prognostic factor. Although not significantly different, lymph node metastasis was recognized more frequently in the high expression group (p=0.07). In conclusion, the findings show that HDAC expression is associated with aggressive behavior of primary gastric cancer, and imply that determination of the HDAC expression status is useful for predicting prognosis in patients with gastric cancer.
